About

Astragalus drummondii is a species of flowering plant in the legume family known by the common name Drummond's milkvetch. The botanist Thomas Drummond first identified the plant during his travels in North America from 1825 to 1835, the year of his death. Astragalus drummondii is one of many plants named after him. Upon the return of samples collected by Drummond to England, his findings were published in Sir William Hooker’s Flora Boreali-Americana in 1840.

Where it grows

Astragalus drummondii is found widely across the American west and Saskatchewan, Alberta, and British Columbia. Its distribution has not changed appreciably since the species was first identified.
